ELECTRIC LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 542,03 3, dated July 2, 1 895.

' Application filed October 3, 1894. Serial No. 4 10i (No model.)

To all whom it may concern:

Be it known that I, THOMAS EDGAR ADAMS, a resident of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvementsin-Electric Locomotives; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvementin electric locomotives, and more particularly to the manner of mounting the electric motor, the object of the invention being to produce simple and efficient means for flexibly supporting the motor on the axles of the car independently of the truck-frame.

A further object 'is to so mount the motor that the vibration transmitted to the car will be reduced to a minimum.

A further object is to so construct a motor mounting and gearing that the weight of the 7 motor will come upon the gear-casin gs, whereby great durability of the axles and journals is had.

A further object is to so construct the mounting as to effect equal freedom of the motor from cramping strain and equal freedom from the dead-weight hammer-blow on the track.

With these objects in view the invention consists in the combination, with car axles, of motors geared therewith and supported by the axles independently of the truck-frame.

The invention alsoconsists in the combination, with car-axles and motors geared therewith, of gear-casings mounted on the axles and connected with the motors, said motors being supported by the gear-casings independently of the truck-frame.

The invention also consists in the oombination, with the car axles, of motor-casin gs, flexible connections between said motor-casings and the axles, a bar resting on said casings, and flexible connections between said bar and casings. g

The invention also consists in the combination, with car-axles, of motor-casings, flexible connections between said casings and axles, a bar having a slidingconnection with said casings, and flexible connections between said casings and bar at points between the bear fiat upon the bar f,

ends of the latter; and the invention also consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter Set forth, and pointed out resent the car-axles, on which the wheels B.

' B are located.

Below the truck-frame Aau electric motor 0 is disposed, the casing c of said motor-casing being made in twoparts normally secured together by means of suitable fastening de vices.

Each motor-casing is provided at one side with lugs or arms 0, each having a perforation for the passage of a rod 0', having a bearing immediately over the axle on integral sleeve 0 projecting from the gear-casings,and each rod 0 is provided with a head e screwed thereon, between which head and arm 0 a spring 6 is inserted, and the heads 6 are held in place by means of nuts e and split keys 6 On the rods 0', between the lugs or ears c-and the sleeves c of the gear-casings, springs c are placed.

A perforated arm 01 projects from the oppo-, site or inner side of each motor-casing at the center of gravity thereof for a purpose pres ently explained. Lugs 6 project from the outer edge or side of each motor-casing centrally between the ends thereof, and between these lugs rollers e are mounted, on which rollers a bar f is placed, said bar being of a length sufficient to extend over the rollers of both motor-casings. In line with the perforations in the arms at of the respective motor-casings the bar f is perforated for the reception of tions of the arms 01 and at their upper ends are made with heads f At their lower ends the rods f are provided with washers d, held in place by means of nutsd and split keys 61 Between each arm 01 and the barfa spring g is located, and between the arms 01 and washers d springs g are located. The heads f on the rods f are made large and normally so that when a curve in the road is being traveled and the front of rods f, which also pass through the perforathe motor swings out of line the large heads on the rods f will be tipped and have the effect of bringing the motor back into line quickly. The bar f is maintained in proper position by means of headed pins h, secured to the motor-casings and projecting through elongated slots h in said bar, with springs it between the bar and pin-heads. Extensions 7L project from the arms 01 of the respective motor-casings into stirrups 71 secured to the barf. With this construction and arrangement, if any of the supporting parts should break, the motor would be sustained by these stirrups and in this manner operated until it can be repaired.

The respective ends of the motor casings are made with openings 1', one half of each opening being made in the respective parts of said casing. In these openings hollow trunnions a" project, each hollow trunnion being made integral with the respective gear-casing D D, or, if desired, said trunnions maybe made separate and bolted or riveted thereto. Each gear-casing is made in two parts normally secured together by means of suitable fastening devices. One end of each gear-casingis pivotally connected with the motor-casing by the trunnions i, and the other end isprovided with the sleeves c journaled on the axles B. The armature-shaftjof the motor projects at both ends through the hollow trunnions v." and have hearings in removable linings 11 therein, the extremities of said shaft also having bearings in removablelinings i located in hollow bosses i formed on the casings 0.

Within each gear-casing D a pinion E is secured to the armature-shaftj and adapted to mesh with gear-wheels E, keyed to the axles, said gearing being adapted to retain the gear-casings in proper position. The pinion E on one end of each armature-shaftj is preferably arranged so as to engage the teeth of the corresponding gear-wheel E slightly in advance of the engagement of the pinion at the other end of the armature-shaft with the corresponding gear-wheel to secure the smoothest running of the gears.

The lower part of each motor-casing is made with double walls to produce chambers k, which constitute receptaclesfor lubricant which may escape from the armature-bearings. Openings Z Z are provided, whereby the accumulated lubricant can be removed when desired.

By mounting the motors independently of the truck-frame, as above described, vibration to the car-body will be reduced to a minimum. By causing the gear-casings to carry the weight of the motors great durability of journals and axles is had. Equal'freedom of motors from cramping strains and equal freedom from the dead-weight hammer-blow on the track is obtained by the manner of supporting the parts as above described.

The car-axles thrown askew by curves or obstructions come quickly to their correct positions as the motors seek the lowest point for their center of gravity, which is approximately in line with the center of support.

My improvements are simple in construction and effectual in all respects in the performance of their functions. v

Slight changes might be made in the de tails of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details of construction herein set forth; but,
